BUCKLE.

Specification of Letters Patent.

Patented Jan. 5, 1909.

Application filed February 13, 1808. Serial No. 415,671.

Tuna whom it may concern: 1 Be it known that I, DARRAGH E .IJANCEY, a citizen of the United States, and resident of Waterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Buckles, of which the followmg is a specification. This invention'relates to an im roved form of buckle, commonly known in t 1e trade as a bag buckle, such as are usually employed u on bag straps, skate straps, and other p aces where a close adjustment and firm enga ement of the stra is required.

t is the purpose oi my invention to devise a buckle for the above purposes that can be used in a variety of places with satisfactory results and constructed so as to uickly take hold of a strap the instant it is re eased, after being threaded through the buckle and tightened; to provide positive means for the engagement of the strap, whereby its'engaging portion is sure to take hold, and finally'to include means for the manuafo eration of the slide to disenga e the same rom the strap when it is desirer to'disconnect the same.

With the above and other minor objects in view I have devised the simple construction shown upon the accompanying sheet of drawings, forming a art of this s ecification, upon which similar 0 \aractcrs 0 reference denote like or corresponding parts throughout the several figures and of which,

Fi ure 1, shows a side elevation of my buc e as applied in use, a connected strap being indicated in dotted lines. Fig. 2, is a plan view of the buckle shown in Fig. 1. Fig. 3, is a disconnected perspective view of the same. Fi 4, is a perspective view of the slide detac ed. Fig. 5, is a modified form of slide, and Fig. 6, is a ccntral'vertical longitudinal sectional view throughthe buckle.

The buckle is formed of two parts of metal, the fraine of which is composed of side portibns 7-7 and cross bars 8, 9 and 10 fol-min r "front and rear openings 11 and 12 througi and out of wh'c I. the strap 13 is threaded. The butt end. 0 the strap is secured to the intermediate cross bar 9 in substantially the manner indicated in Fi 1 and the rear )01'- t I I tion including the cross bar 10 is disposed upward as sblown so to per-nut the opening 12 to be used as a loop under and out through l which th free end ofthe strap may be disosed, after bein threaded up through the orward loops of t e buckle am engaged.

The slide 14 is provided with extensions 15 which are curled around the side portions 7 of the frame to form a sliding engagement of the slide with the frame, and further comrises a forwardly extended ortion includmg side bars 16 and a cross ar 17 so connected and arranged as to form a loop 11 of a size and shape adapted to register with a portion of the opening 11, and through which the strap is first assed when threaded from the underside of t 1e buckle. The inner edge of the cross bar 17 may be deflected downward to insure a more positive engagement thereof with the strap, and in the edge on opposite side of loop are formed teeth 18 that are deflected upward to engage the inner edge of the u per cross bar 8 of frame, when the slide is s hoved forward, and not connected with the stra The rear side of tlie slide is provided with an arm that is disposed'upward in line with the normal osition of the connected strap when three ed through the loops before mentioned; A series of teeth 20 may be formed in the top edge of this upwardly disposed arm 19 as shown in the drawing, to

etter engage the strap and insure the closing of the slide and likewise to form enga 'ng means for its manual operation, thoug in practice a plain edge like that shown inFig. 5, is perfectly practicable. In Fig. 5, I have also shown a downwardly deflected end 21 ual operation of the slide, and thus forms a. external thumb latch which is not liable to release the strap by accidental pressure.

The operation of the buckle is as follows:- Assumin the butt end of the strap to be connects to the cross bar 9 of the frame and a trunk, ackage or other object and the free end of the strap threaded up through the 100 s 11 and 11, it would next be drawn up tig t and pressed down upon the top edge of the arm 19. By reason of the enga ement of the strap with the said top edge of t 9 arm a release of draft upon the free end of strap would cause it to relax and draw the slide forward in a way to cause the teeth 18 of the forward edge of the slide to enga e the underside of the strap, and force it against the ed e of the cross bar 8, and further deflect it against the inner edge of the cross bar 17. The tension of the strap when in engagement with the said edge also further serves to draw the body portion of the strap carried around 9.

which serves as a further means for the man- IOU IIE

the slide forward and to retain it against the strap in a way to p 'ent its releasernent un til untin'r-nded from the loop, and the arm 1!! or end 21 or slide n'ianually engaged and slid back to free the strap.

Having thus described my il'lVUlltiUI] what I claim and desire to secure by Letters P atent is 1. A buckle, comprising a frame having side bars and cross burs, a slide connected to the side bars and having a loop of a size and shape substantially like that of the forward opening through the frame and a strap enaging edge, and an arm disposed upward mm the rear side of the slide or the engagement oi the strap and the manual operation of the slide.

2. A buckle, eomprisin a frame having side bars and cross bars an a loop in the rear ortion of the frame, a slide connected to the rame and having an edge to engage the strap, and an arm disposed upward and having a series of teeth to enga e'the underside of the strap when threaded t rough the loop to insure the engagement of the edge with the strap when the latter is under strain.

3. A buckle, comprising a frame having side bars and cross bars, one of which is in a plane above the others to form a raised loop at the rear end of the buckle, a slide conneoted to the opposite side edges of the frame, and having a toothed engaging edge.

shape suhstantiall along the forward side and an arm deflected upward from the rear side and having a vse lies of teeth for the engagement of the strap to SUCLH'H the same when under strain.

4. A buckle, comprising a frame having side bars and cross bars, a slide connected to the side bars and having a loop of a size and like that of the forward opening ti'n'ough t e buckle frame, the inner edge of the forward transverse portion of the loop being disposed downward and the op )0- site edge of the loop being serrated and disposed upward and an arm dis osed upward mm the rear side of the slide or its manual operation and the engagement of the strap;

5. A buckle, comprising a frame having side bars and cross bars, a slide connected to the side bars and having a loop of a size and shape substantially like that of the forward 0 ")ening throu h the frame, a strap engaging e ge, an arm isposed upward from the rear side of the slide for the en a ement of the strap and a downwardly d e ected portion along the forward ed e of said slide for the manual operation of t e same.
